After the original Ben 10 series, they came out with Ben 10 Alien force. The first season was weak, but the rest were great, and now this new series really pulls all the cool action together!

Ben 16 Ultimate Alien is definitely a nice farewell to this version of Ben.

There are a lot of people out there that simply hate on this series because it did something very bold, it tried to expand the storyline and universe of Ben 10 and did it in a dark tone. Sure the original series was a bright and flashy thing with laughs a plenty, but when you begin to grow up, you notice that the world isn't the lurid colours you saw as a kid and begin seeing the world as it is, not what you wish it was. This is what the core of UA is and it's a welcome addition to western animations horrible standing on animation 'only being for kids so it better not be risqué'. Wonderful addition to the series and a good watch.

This show is terrible the only reason is still on the air is cause cartoon network won't let this peice of **** series die. if you actually enjoy this you are probaly just another cartoon network fanboy who only watches bad shows this is a insult to good shows on tv like big brother. a porno has a better plot than most of the episodes on this show
